Do not leave your candle unattended and blow out the candle when it has reached the bottom otherwise the votive will become very hot.

Trim or pull of the ends of the wick when relighting your candle, this will help the candle to burn evenly.

When first lit, make sure you allow the candle to burn to the edge of the votive. If you blow out the candle before this point, it will only burn up until this point when next lit making a pool of wax which can cave in and destroy your candle.
